The present invention relates to new and useful improvements in airplanes, and has for its primary object to provide, in a manner as hereinafter set forth, a machine of this character comprising novel propulsion means.

Qther objects of the invention are to providean airplane of the character described which-will be iv ly s mple in constructi n. strong. durable, safe and reliable in operatiomand which maybe produced at low cost.

All of the foregoing and still further obiects and advantages of the inventionwill become ap-v 'rearpropellersonsaid'crankshaftsIpush'The parent from a study of the rollowing speciiication, taken in connection with the accompinying drawings wherein like characters of reference designate corresponding parts throughout the new eral views, and wherein:

Figure l is a top plan view of an airplane constructed inaccordance with the present invention.

Figure 2 is a view in front elevation thereof. Figure 3 is a view in horizontal section through one of the wings and a portion of the fuselage.

Figure 4 is a vertical sectional view through Figure 5 is a detail view the propeller shafts. 1

Referring now to the drawings in detail. it will be seen that the embodiment of the invention which has been illustrated comprises a body or in perspective of one of fuselage I. which fuselage may be of any desired construction and dimensions. The fuselage i is provided with a suitable'landing gear which is d signated generally by reference numeral 2.

Pairs of wings I Project laterally from thefuselagei at longitudinally spaced points. The usual tail assembly I is providedon the rear end portion ofthefuselage i.

Mounted longitudinally in each wing I is a series of spaced. parallel crank shafts I which emerge fromthe leading and trailing edges of the wing. The crank shafts I are iournaled in bearings I. Propellers I are fixed on the end portions of the crank shafts l forwardly and rearwardly of the wingy In theembodiment shown. drive crank shafts I are rotatably mounted in the fuselage'i. adjacent the wings I. Connectingrods I operatlvely connect the crank shafts I and I for rotation in unison. High-speed outboard engines II are construction and arrangement is such that the machine will be capable of exceptionally high speed. Any suitable means may be employed for lubricating the engines and other moving parts.

It is believed that the many advantagesof anaccordance with the presairplane constructed in ent invention will be readiiy'understood, and although a preferred embodiment of the machine is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts maybe resorted to which will fall within the scope of the invention as claimed. What is claimed is:

1. Ari-airplane comprising a fuselage, pairs of wings projecting from the fuselage. at longitudinally spaced points, series of spaced, parallel crank shafts mounted longitudinally in the wings and emerging from the leading and trailing edges thereof. o llers fixed on the end portions of the crank shafts. rods connecting the crank shafts for operation in unison, and means for actuating the crank shafts, said means including crank shafts rotatably mounted in the fuselage adjacent the wings, and engines mounted outboard on the fuselage and operatively connected to the secondn'amed crankshafts.

2.An airplane comprising a 'mseugecmgs' mounted on said fuselage. 'spaced crank shafts mounted ineach wing parallel with the longi- -'tudinal axis of the fuselage, propellers-on said crank shafts. a crank shaft mounted in the fusel ge adjacent each side of the latter and parallel with thelongitudinal axis of the fuselage, an enthe latter and rearwardly of each wing, means ted on the fuselage! rearwardly f wings I. which engines may be cooled in am! suit; able manner. The engines II drive the crank shafts I through chain and sprocket connections lue mounted on each side of the fuselage outside operatively connecting said engine to the secondnamed crank shaft, a rod connecting the secondnamed crank shaftto-oneoftheflrst-namedcrank shafts. and rods connecting .said first-named inunison.
